1 Kings 11:27-29

27Now this is the reason why he rebelled against the king: Solomon built the Millo (fortification) and he repaired and closed the breach of the city of his father David.

28The man Jeroboam was a brave warrior and when Solomon saw that the young man was industrious, he put him in charge of all the forced labor of the house of Joseph.

29It came about at that time, when Jeroboam left Jerusalem, that the prophet Ahijah the Shilonite met him on the road. Now Ahijah had covered himself with a new cloak; and the two of them were alone in the field.
